How-To Geek

When you’re managing a public computer, you need a special kind of tool. You need a way to reset that computer back to a clean state every time it boots so no one can make any harmful changes.

Commercial solutions like Deep Freeze offer this feature, and Microsoft once offered it via its Windows Steady State tool for Windows XP and Vista. However, Windows Steady State has been discontinued and doesn’t work with Windows 7.

We’ll be using Reboot Restore Rx for this, as it supports both Windows 7 and Windows 8. Steadier State is another solid option, but it only works in Windows 7, and even then only with Windows 7 Enterprise and Ultimate.

Installing Reboot Restore Rx

Before installing Reboot Restore Rx, be sure that your system is in the clean state you want to “freeze” it in. Install the software you want, update it, arrange the desktop, and do everything else you need to do. Of course, you can temporarily disable Reboot Restore RX to update your system state later.

While installing Reboot Restore Rx, you can select the partitions you want to restore at reboot. This allows you to have a separate data partition that won’t be touched, if you like — or you can set Reboot Restore RX to restore all your partitions.

The computer will restart to install the Reboot Restore Rx recovery environment. Whenever the computer boots, it will first boot into this environment, where the Windows drive’s state will be restored automatically before the computer boots normally. To undo any changes, you’ll just need to reboot your computer.

Preventing Users From Disabling Reboot Restore Rx

Reboot Restore RX is fairly simple to use. Its biggest problem is that it can be disabled without a password. By default, Reboot Restore Rx launches in the system tray each time you log in and provides you with a right-click option that allows you to easily disable the protection. If you’re using Reboot Restore RX to lock down a public computer, that’s not a good idea.

Your best bet is to prevent the Reboot Restore Rx icon from starting at boot by disabling it in MSConfig or a startup manager like the one found in CCleaner. If you want to disable the protection, you can then manually launch the Reboot Restore Rx application by browsing to it on your hard drive. The computer’s users could theoretically do this as well, but this provides more protection. You could even lock down the folder containing the Reboot Restore Rx application and require special user permissions to access it, which would prevent people from disabling it even if they went out of their way to look for it.

If you need to launch it later, you’ll find the system tray program installed at C:\RebootRestoreRx\program files\Shield\shieldtray.exe

Updating or Changing Your System

Of course, you’ll occasionally want to modify your system. Whether you want to install updates, add new software, delete files, or do anything else on your computer, you’ll have to disable the feature. This is a very simple process.

First, disable the Restore on Reboot option from the system tray icon. If you have disabled the system tray icon, you will need to launch it manually.

Next, make your changes. Update your software and do everything else you want to do.

After you’re done, right-click the system tray icon again and select Restore on Reboot. When you do this, it will inform you that it’s making the current system the new baseline state.

Accessing the Boot Console

At the Reboot Restore Rx splash screen, which will appear every time your computer starts, you can press the Home key on your keyboard repeatedly to access a special menu. Anyone with access to the computer could theoretically do this, but they would need to know they have to press the Home key — it isn’t displayed on-screen.

You can choose to Uninstall Reboot Restore Rx from here. This will remove Reboot Restore Rx from your system.

Reboot Restore Rx isn’t the most secure and enterprise-ready option, but it’s very easy-to-use and runs on a variety of different Windows systems. Reboot Restore Rx is ideal for people who want their computers to be in the same state every time they boot and don’t want to purchase the Ultimate edition of Windows or perform a more complicated setup process, whether they’re a business with a few public computers or parents who want their childrens’ computers locked down.

I prefer ToolWiz TimeFreeze. It's a little more basic than RRRx in that in only allows the main system drive to be frozen and restored, but it allows for password protection so it cannot be tampered with. Though DeepFreeze was always my favorite, TimeFreeze is pretty great for being freeware.

Also, the splash screen appearing every time the computer starts could be annoying to some extent and would also result in some increase in Boot Time.

I used to use a 'recovery card' which was a small PCI add-in card which would save any changes to the Windows XP partition at the end of the hard drive space. After rebooting, the changes were wiped. No additional software/drivers were necessary. However, I believe it only worked for FAT32 file systems, not NTFS. It worked great at the time, however. I could literally re-format the hard drive, reboot, and it was like it never happened.

If you search eBay for 'PCI recovery card', you can still find them available for sale.

The post to which I replied is my mistake and i am sorry for that. Actually I wanted to tell about software Deep Freeze. In that there is good level of security where in no normal can alter Deep freeze setting.
